Greencrete looks and performs the same as normal concrete, however, it reuses recycled glass in place of quarried sand and gravel materials to reduce waste.
"We're excited to be the first Hunter council to trial Greencrete, reusing recycled glass to reduce our environmental impact and ensure ongoing sustainability in our building works," Council's capital works section manager Philip Miles said.
"We have elected to trial this new material in a prominent location so the community can view and provide feedback on it, and the works currently underway at Tanilba Bay presented the perfect opportunity.
"For our trial, we will be replacing the sand content of normal concrete - which makes up about 25% - with recycled glass, to be used on traffic islands at Tanilba Bay.
"Port Stephens will be the first Council in the Hunter to reuse recycled glass in this way, and we're keen to lead the way in developing sustainable practices for our projects now and into the future."
Council is partnering with local business Redicrete to produce and deliver the new Greencrete, which was poured for the first time in Tanilba Bay this week.
